IPC: D03D51/20
Filed: 1948-04-16
Abstract: 655,850. Warp stop-motions. MAISON NEYRET. April 16, 1948, No. 10601. Convention date, Dec. 29, 1947. [Classes 142(i) and 142(iv)] [Also in Group VIII] A warp stop-motion comprises a rotating, roller on which a broken thread is wound to close electrical contacts and stop the machine. The roller 22 which is covered with velvet or like material, extends the entire width of the warp 5 and is rotated in the direction of the arrow f2 by worm gearing and bevel gearing 35, 38, 42, 43 from a shaft 14 driven by a belt drive 12, 13 from an electric motor 11. Rocking levers 24 supporting the roller 22 are each provided with a roller 27 in contact with a cam 31 which causes the roller 22 to brush against the warp to detect a broken thread. When a broken thread is drawn out of the plane of the warp it moves one of a series of contacts 46 against a connecting bar 50 which causes a relay 57 to be energized and a switch 54 to be opened to stop the motor. The contacts 46 are formed of wire and are V-shaped and secured to a bar 48. Each contact is arranged so that a portion of it overlaps the adjacent contact and a broken warp cannot pass between two contacts and fail to stop the motor. In an alternative construction, the roller 22 may have longitudinal slits along its surface connected to a source of vacuum whereby a broken thread is held against the roller by suction. In a machine having a warp which swings about an axis, the roller 22 may be stationary and positioned to engage the warp during its swing.

Abstract: 118,603. British Westinghouse Electric & Manufacturing Co., (Assignees of Candee, A. H., and Hibbard, L. J.). Aug. 7, 1917, [Convention date]. Controlling arrangements for collectors.-An electro-magnetic relay device 8 for use with electro-magnetically-operated means 6 for lowering the trolly 1 of an electrically-propelled vehicle ensures that, when the hand-operated switch 7 controlling the operating-circuit from the batery 45 is closed, this circuit is not completed and consequently the trolly is not lowered if an overload exists on the system, but the circuit is completed and the trolly lowered as soon as normal conditions are restored even if the hand-operated switch has meanwhile been moved back to the " off " position. The relay comprises a core 11 having a winding 12 energized from the supply circuit, the core co-operating with a pivoted armature 17 normally resting on a contact 25. With excess current in the winding 12, the armature is raised. lifting a rod 13 which carries two bridge contacts 15, 16. The bridge 15 is thereby removed from the contacts 26, 27 which are in the trolly-operating circuit through the switch 7. The bridge member 16 is also raised and tilts the forked contacts 30, 31 about their pivots 33, 39 but does not bridge these contacts, as their upper limbs are provided with insulating-material 34, 37. The forked contacts are held in the deflected position by latches 36, 41, and when the overload is removed so that the armature 17 and rod 13 desoend, the member 16 bridges the lower forks of the contacts 30, 31, thereby completing an actuating-circuit for the trolly through the magnet core and through the armature to the contact 25 independently of the switch. To re-set the switch, the latches 36, 41 are depressed.

Abstract: 161,449. Robinson, J., and Crowther, H. L. April 23, 1920. Directive signalling; bearings, determining; thermionic amplifiers and detectors; audible reception of unmodulated continuous waves.-Relates to a receiving system for analysing the direction of propagation of incoming signals. Two rotatable frame aerials 1, 2, mounted at an angle to each other, are connected to the grids 3, 4 of two high-frequency or rectifying amplifiers. The secondary winding of a transformer in a low-frequency oscillating circuit 11 is connected across the grids 3, 4, the mid-point being joined to the filaments of the valves through a potentiometer 15. With the arrangement, one half-cycle of the audible-frequency oscillation in the circuit 11 raises the potential of the grid 3, whereas the second half-cycle raises the potential of the grid 4, the result being that the signal energy received by either of the coils 1, only passes through to the telephones 12 on the peaks of the lowfrequency oscillations. The required direction of propagation is determined by swinging the frame aerials until the combined effect of the received signals produces a smooth or pure tone in the telephones, thereby indicating that each of the aerials 1, 2 is equally inclined to the source of the incoming energy.

Abstract: 315,904. Laporte, Ltd., B., Weber, I. E., and Bennett, A,. N. C. April 17, 1928. Pigments.-In the manufacture of a pigment by calcining a mixture of titanium oxide and barium sulphate the mixture is prepared by adding barium sulphate to, or forming barium sulphate in, a fine dispersion of titanium oxide and coagulating the dispersed oxide. For example, a precipitate of titanium oxide may be dispersed by hydrochloric acid, nitric acid, barium nitrate, barium chloride, or strontium chloride, and to the dispersion is added barium sulphate in sufficient quantity to produce a final product containing about 70 per cent of barium sulphate; the addition of barium carbonate coagulates the oxide, and after the suspended matter has been allowed to settle it is separated from the liquor, washed, and calclined. By mixing a soluble barium salt with the titanium oxide dispersion and adding an alkali sulphate chemically equivalent to the barium salt barium sulphate is precipitated and the titanium oxide coagulated.
